Ergonomic Foot Switch Design for Electric Biomedical Devices (Bipolar Cautery, Medical Electric Drills and Saw)

Nihal Handigol | Mrunal Ketkar [2]

Abstract: Surgeons around the world routinely use medical instruments which require control of switching on and off or adjustment of speed of the instrument using a separate sensor, usually in the form of a footswitch. These foot - switch sensors, although reliable, are bulky, experience loss of contact during use, restrict movement of the surgeon around the operating table and cause discomfort on long continuous usage. A novel device was designed to overcome these shortcomings utilizing a new force sensor and piezoelectric sensor. The force sensor and piezoelectric sensors are coupled and placed at the base of a sleeve designed to snugly fit over the great toe of the surgeon. The force sensor measures the amount of force exerted by the great toe and the numerical value is processed in Arduino Nano which forwards the value to the existing electric system. The piezoelectric sensor acts as a safety check which activates or deactivates the device by double tapping of the toe, thus preventing accidental activation of the device. The device decreases the fatigue associated with long usage of the device, eliminates the bulk factor and eases movement of the surgeon around the OT table.
